Patented Oct. 10, 1905.

Application filed March 12. 1901. Serial No. 50,858.

To all whom, it may concern:

Be it known that we, Tr-n iorrnnn Duoonsso, a resident of 219 Rue deVaugirard, and FER- DINAXD RODARY, a residentof No. 53 Rue de Vaugirard,Paris, France, citizens of the Republic of France, have invented certainnew and useful Improved Means for Operating and ControllingRailway-Points, of which the following is a specification.

Our invention relates to improvements in means for operatingrailway-switches electrically.

Our invention includes the combination of a transmitting apparatus andan operating mechanism electrically connected by wires and any desirabledistance apart, in which the transmitting apparatus automatically checksthe movements of the operating mechanism and in which the operatingmechanism checks the movements of the transmitting apparatus, thusinsuring the locking of the switches that are not visible to theoperator at the transmitting apparatus.

Our invention, furthermore, includes the novel mechanisms by which thesemeans are carried into effect.

The object of our-invention is to provide the means by which railwayswitches or points may be operated electrically in such a manner thatthe operator may only make one operation at a time, and has automaticand visible checks by which he may know that such an operation has beencompleted; furthermore, the means for giving various alarms should theoperating mechanism or the tracks connected with the instrument in hischarge be tampered with or obstructed.

- Accompanying this specification are the illustrations of themechanisms by which these objects are carried out, in which Figure 1 isa plan view of the operating mechanism. Fig. 2 is a section of thedistributing-switch u on a line formed by the inside of supportu of Fig.3. Fig. 3 is a front elevation of the distributing-switch u, a part ofthe operating mechanism. Fig. at is a side elevation of the transmittingapparatus. Fig. 5 is a perspective side view of lever B and mechanismcontrolling its movement, a part of the transmitting apparatus, detentsB and B broken, section-lined, and dotted in full to show theirrelation. Fig. 6 is a detail front elevation showing a plurality oftransmitting-levers for controlling the operation of duplicate sets ofmechanism. Figs. 7, 8, 9, and 10 are plans to show the generalarrangement, the relative positions of mechanisms, and wiring diagramsindicating the direction of current in conductors at four possiblepositions of the levers and switches.

Referring to Fig. 1, our improved apparatus comprises a table or framing(I, provided with supports a and carrying at Z) a series electric motor,of which 6 is the field-magnet, 6 the armature, and Z) Z)" the brushes.The motor-shaft is connected with the worm (Z through a coupling a, andthe said worm gears with the wheel a. Said wheel is adapted to turnfreely onits spindle a. This wheel a carries at an eccentric point aroller which engages in the cam-like slot f fiFof alever f, keyed upon ashaft g, upon which is likewise keyed a lever it, terminating in athreaded head It, which allows the length g it of the lever to beadjusted. This combination of parts constitutes the apparatus for movingand locking the point.

The wheel a carries a concentric groove 0 which is of medium radius,united at its extremities to other grooves e" a of smaller and largerradius. This groove a engages with a finger Z of a lever v1 Z movableabout a fixed axis '17. This lever carries two insulatingrollers '2' Z",situated between the springs j 3' j, which are fitted in a suitablefixed insulating-support f, with respective contacts j j j j. Thesprings f j are set in such manner as to make contact with theirrespective contact-bearingsj and j if no obstacle is opposed thereto.This part constitutes a switch controlling the position of theroller-pin c and thereby controlling the locking of the railway-switchesand producing also the stoppage of the motor at the desired moment byshort-circuiting the armature.

The apparatus also carries a lever 7t, keyed on a shaft it", carryingtwo arms with regulating-screws Z2 la. The extremities of these screwsare fitted with insulated ends, and they are situated in the same planeas the springs Z Z and their respective contacts or bearings Z Z. Thesesprings have an initial tension suflicient to keep them freely away fromthe contacts or bearings. This part constitutes thswitch which controlsthe position of the switch-rails.

a is the distributing device, which is also shown in detail in Figs. 2and 3. This distributer is moved by a polarized electromag netic deviceformed, for example, of a double T-iron bobbin 1:, the spindle of whichis adapted to turn freely in supports a, this bobbin IIO being placed inthe fixed magnetic field of the magnets with their expanded pole-piecesM The spindle of the bobbin is hollow and gives passage to the twoinsulated wires or extremities of the bobbin winding. This spindle isrigidly connected to two arms 10*, upon which is fixed a piece nof woodor other insulating material provided with two series of metalliccontacts a n and n a of. The contacts'n W are electrically connectedtogether, as are also if andn Further, flexible wires lead from thesecontacts, the connections of which wires will be described hereinafter.m m m m, fixed to an insulating-support m, are adapted to make contact.The bobbin 24 carries a finger a, which limits the angular travel bycoming againstthe screws 166107. In combination with theshort-circuiting switch for the armature the distributer n serves tomake the required connections for determining the direction of rotationof the motor and providing for the stoppage of same. It therefore formspart of the means of control, as will be explained later.

The operation of the apparatus is as follows: Referring first to thedistributer, in Fig. 2 the bobbin is maintained in the position shown bythe constant action of the fixed magnetic field upon the bobbin a, whichaction operates in the direction of the arrow a". If a sufficientlystrong electric current be sent into the said bobbin, the resultantaction will depend upon the direction of this current. If the currentpasses in such direction as to turn the bobbin in the direction of thearrow a the bobbin does not move, but is held securely in its positionagainst the stop a WVith a current of reverse direction the action is inthe opposite direction to the arrow a and the bobbin turns on its axisuntil it comes against the screw 1/. In its movement the bobbin carrieswith it the arms 10* and the piece n, carrying the contacts. The resultis that the springs m m m m are opposite the one or the other of theseries of contacts a n or n n 92 according to the direction of thecurrent last sent through the bobbin 14.

Referring now to the motor, the motor 7) (which is mechanically in rigidor driving connection with the worm (Z) is susceptible of threedifferent states or conditionsnamely, a state of rest, rotation to theright, and rotation to the left. In the first case the wheel e is lockedby the worm. In the second case the wheel is driven by the worm andturns in the direction of the arrow 6. In this movement the roller 6working in the slot f, moves the lever f from the position shown in fulllines to that shown in dotted lines, the consequence of which is toproduce a similar movement of the lever g h It and, further, theoperation of the lever z' a" d in such manner that when the roller 6leaves the concentric portion 7 and enters the straight portion f ofUpon these contacts rubbing springsthe lever f the finger is at thecommencement of the part 6 of medium radius of the groove 6* 6 6 andconsequently the three switch-springs j j are put by the rollers 11 ainto an intermediate position, such that they do not touch theircontacts. Matters remain in this state so long as the roller 6continuesits movement in the straight slot f. Then as soon as thisroller enters the curved portionf the motion of the finger d is deviatedby reason of the deviation of the groove from 6 to 6 this bringing therollers i 6* into the position shown in dotted lines, such that jmakescontact with and 7' with The part played by these sets of contacts willbe explained later. The third state or condition of the motorviz.,rotation to the left produces in an inverse direction all the effectsjust describedthat is to say, the movement of all the parts from theposition shown in dotted lines to that shown in full lines.

The action of the lever k k will be further explained in describingthegeneral operation.

Referring now to the transmitting apparatus, Figs. 4, 5, and 6, thetransmitting apparatus placed in the signal-box or central stationcomprises a framingA with a table in the form of a segment of a circleA, at the center of which is a fixed spindle A and covered by a piece Awith projections A A A. Pivoted upon the spindle A on the back side oftable A is the transmitting-lever B B B with a lug B toward the table Aand hereinafter referred to, also two symmetrical sets of detents orcatches. One set B and B are link-shaped, right and left handed, andpivoted on pins next to lever B, so as to slide along the surface oftable A. Detents B and B are provided with springs B and B, the end ofeach of which bears on another detent B and B of similar outline, butfiat and independently movable on the same pin. These slide along thetop of and are adapted to en:

gage with a plate E, hereinafter referred to. It is evident that thoughthe detents are movable independently the detents B and B will raisedetents B and B by means of the springs if not obstructed. A bolt C,movable vertically in the framing A, normally presents its upper end atthe level of the table A and in the path of the grooved detents B and BThis bolt is cut away at G at such a height that the lug B of thetransmitting-lever shall not be able to pass if the bolt is not raised,and, on the other hand, when the boltisraised the lug B can pass; butthe detents Bland B according to the direction of the movement, will bearrested by the projection of the bolt above the table A. Anelectromagnet D D, fixed to the framing A, has an armature D which issupported upon one of the poles D, and this armature is prolonged by thelever D which engages. with the lower portion of the bolt and actuatessame. WVhen the electromagnet D D is excited, the bolt is raised.

\Vhen this electromagnet is not excited, the weight of the bolt causesit to descend and draws the armature away from the pole 1). Thus theelectromagnet D D controls the lever B by allowing or preventing itsmovements. The armature D is also prolonged by a rod D, connected by therod D to a small lever D D, pivoted at D and carrying at D an indicatorwhich is adapted to appear opposite a window D' when the electromagnetis excited. A plate E is applied against the framing A and is adapted tomove about the spindle A This plate has the same circular form as thetable A; but it carries at its extremities projections E E and teeth EE". The framing A carries an insulating-plate F, which supports areversing-switch formed of two metal arms G G, movable about thespindles pivoted at G and G fixed on the plate F and actuated by theconnecting-rod by means of electrically-insulated pins G". Thisconnecting-rod is pivoted at G to the plate E. The arms G G are arrangedto make contact with the contact studs 01' bosses G G (i according totheir position. To the connecting-rod G is fixed a ring G9, and,further, two collars G and G are mounted freely upon this connecting-rodbetween the ring G and the pivoted joint G Between these collars is astrongly-compressed helical spring G, which tends to force the saidcollars apart; but they are retained by catches H H The catch H isformed by the end of a lever H H H Fig. 5, pivoted at H and pressed bythe spring H so as to hold the collar ii in place, while the lever H His pivoted at H" to a fixed point of the framing A and at I to aconnecting-rod H itself jointed at H to a detent H H H, pivoted at H andpressed by the spring H, holding the collar G in place by the catch Hformed by the end of the part H The extremities H and H of the saidlevers project above the circular table A to a less extent than theprojection E E of the plate E. These said extremities, moreover, passbehind the plate E and into the path of the detents B B while the plateE is itself in the path of the detents B" B". The movement of thereversing-switch G G is in one with that of the plate E. which isactuated directly by the detents B* B during the movement of the leverB, while the switch G G may be independently operatedl is jointed at Bto the transmitting-lever.

The plateFalso carries a relay J of very great resistance, the armatureJ of which is adapted to return by its own weight against the stop Jwhile the relay when excited brings the armature against the stop J Thetransmitting-lever is jointed at B by a rod K to a bar K, passing intothe lockingtable L. The object of the locking-table is to prevent thepossibility of moving the lever B to the position occupied by anotheranalogous lever, such as X, Fig.6, commandinganother switch. Thus inFig. 6 the bar K has a groove or slot K into which enters the block K ofa bar K sliding at right angles to the firstmentioned bar, the saidblock bearing against the bar X of the other lever, which bar X has acorresponding groove or slot at that is to say, at a position such thatit would be necessary to first completely move this lever X to bring thegroove X opposite the block K* and permit the movement of the lever B.Now it will be hereinafter seen in the course of this description thatin consequence of the arrangements of our system the lever B can neveroccupy a position which is not in accordance with the actual position ofthe corresponding point or switch and that in particular this lever Bcannot be put over to the full extent unless the point or switch itselfhas entirely assumed the desired position.

The complete installation of an apparatus coupled up with a switch isshown diagrammatically in Fig. 7, as well as that of the correspondingtransmitting lever. The two switch-rails are at o and 0 connected by thetie 0 The rails are at 0 and 0". A connectingbar or o1)erating-barconnects the lever g it with the joint of the tie. This is the mode ofrigid connection; but in certain cases where it is required that theswitch-rail should be able to yield and where an intermediate springdevice is employed the bar p is connected to the said spring apparatus.In all cases one of the switch-rails o is connected to the lever 1 K1 bya connecting-bar or controlling-bar q. The transmitting-lever isconnected by four insulated conductors with the switch apparatus. Two ofthese conductors 1" r (indicated in heavy lines) constitute the electrictransmission-circuit acting upon the motor. The two other conductors 1"r (shown in dotted lines) each form in combination with the first-nameda circuit for controlling the operation of the switch-rails and ofvarious other parts of the apparatus.

At the transmitting-station the electricity is furnished by a battery ofaccumulators s or other source of continuous current, one pole beingconnected to the contact-surface I" and to the coil of the relay J, theother end of said coil being connected to the contact 1. The same poleis also connected, through a shunted tremulous bell t, to the body ofthe relay J, and consequently to its armature J-. The second pole of thebattery 5 is connected to the contact-surfaces I 1 to the center G andthrough -the electromagnet D D to the stop or bearing J The centers Gand I are connected together. The line-wires 1" r are connected,respectively, with the contacts G and G The contacts Gr and G areelectrically connected together by the wire 00. The controlling-wires rr are connected, respectively, to I and 1 In the switch apparatus thelinewire 9" is connected to the rubbing contact m the line wire 7' tothe contact a and through the bobbin u of the distributer to thefield-magnet Z) of the motor. The other end of the field-magnet coils isconnected to the spring 9' and with the contact m. The brush 6 isconnected to the contacts a n and with the contact-bearing 7' The otherbrush 5* is connected to the contact-bearing j and with the contacts a02. The controlling-wire r is connected to the spring Z, thecontact-bearing Z to the spring 7' and the contact-bearing to therubbing contact m The controllingwire 9 is connected to the spring Z,the contact-bearing Z to the spring f, and the contact-bearing f to therubbing contact of.

Figs. 7, 8, 9, 10 will serve for illustrating the operation. Fig. 7shows the whole apparatus in its normal position with the switchrail 0'applied against the rail 0 for, say, trains to pass on the main line.Fig. 8 shows the position of the parts during the movement of thepoint-rail 0 from its normal position. Fig. 9 shows the switch-rail 0setfor the passage of trains to the branch line. Fig. 10 shows the casewhere an obstacle prevents the entire movement of the switch-rail.

We will first follow Fig.7. In this condition a current (indicated bythe arrows) passes from the battery 8 through the relay J the switch II", the line W, the contact Z Z governed by the point-rail 0, thecontact j f, governed by the position of the roller 6 the rubbingcontact m the contact of, and here the current divides into twoportions, the one going through the rubbing contact 772 the line 7*, theswitches G G I I to the other pole of the battery, the other portionfrom the contact a to 72 through the contact j j, the motor-magnet Z,the bobbin u, the wire T and by g g g to the other pole. The relay J isexcited, and its armature is moved away from the bearing J Theswitch-rail 0 is kept locked in this position by the presence of theroller 6 in the curved portion f of the lever f. If during thiscondition of things an external force capable of distorting the bar 19(or of overcoming the spring device if the switch is provided therewith)is applied to the point-rail 0 and causes same to move away from thecorresponding rail 0 the mechanical combination of 0 0 0 with the bar 9and the lever Z0 Z3 transmits the movement to the interrupter Z Z thecontact of Z Z is broken,

and the current no longer passing in the relay J the armature J fallsback by its own weight upon the bearing J At this moment thecurrent ofthe battery passes through the bell z, to the body of the relay J and byJ J through the electromagnet D D and returns to the other pole of thebattery. The bell 2. operates, and at the same time the electromagnet DD being attracted causes the indicator D to appear in the window D. Theperson in charge of the signal-box or central station is thus warnedwhen the switch is half-open. To move the switch-rails so as to closethe main-line track and to open the branch track, the lever B is putover from the position Fig. 7 to the position shown in full lines, Fig.8, in front of the projection A In this movement the said lever B bringsthe switch Ifrom I upon 1 the switch I resting on 1 At the first momentthe lever B cannot be put farther forward, because the lug B bearsagainst the bolt C; but as soon as it is in the said position thecurrent of the battery 8 passes through the switches I I I G G, the line1*, and then (the switch apparatus being still in the position shown inFig. 7) by the rubbing contact m the contacts n M, the contact ,7" j,the field-magnet coils Z), the bobbin u of the distributer, and returnsby the wire T the contact bosses or studs g g, the switch g to the otherpole of the battery. Then the current passing through the bobbin ucauses it to move the distributer n into the position indicated, Fig. 8.In this condition the current (indicated by the arrows, Fig. 8) passesfrom the rubbing contact m by the contact of to the brush Z2 through thearmature, the brush 6", the contact 729, and the rubber m, the excitingcoil or inductor Z), the bobbin a, and, as before, to the battery, andcauses the motor 6 to turn to the right, this causing the turning of thewheel 6 in the direction of the arrow 6 The roller 6 in its turncommunicates motion to the lever f, which through the medium of thelever g h and the bar 19 moves the switch toward the rail 0*. It must beremarked that at the commencement of the rotation of the wheel 6,starting from the position Fig. 7, the fingert' is guided by the smallradius-groove 0* into the part c of medium radius. The insulatingrollersthus put the springs 1', f and 1' into an intermediate position, wherethey are out of contact. On the other hand, as soon as the movement ofthe switch commences the bar 9, acting upon the lever Z375, moves thescrew 76 from the spring Z, and this latter interrupts the contact Z ZThe distributer n itself in passing from the position Fig. 7 to theposition Fig. 8 has insulated the rubbing contacts m Consequently fromthis moment the controlling-current, which we have indicated by arrows,Fig. 7, has ceased to pass through the relay J. The armature J hasfallen upon the contact J thus closing the battery-current throughthetremulous bell t, which operates the electromagnet D D. The

Too

armature D of this electromagnet is attracted and the bolt C is raisedand presents the slot or groove C for the passage of the lug B The leverB can then be pushed farther forward, as far as the position shown indotted lines, Fig. 8, where its catch B is arrested by the bolt (J,projecting above the table A. In passing from the position shown in fulllines to that shown in dotted lines, Fig. 8, the only change produced bythe lever B has been to carry the switch I from I on to 1 The handle B,withwhich the lever B is provided, in striking the stops or projectionsA A, limits the stopping-points corresponding to these two positions ina manner which is felt by the hand of the operator. The lever B cannotbe put over farther than the position shown in dotted lines so long asthe bolt (1 remains raised; but as soon as the complete movement of theswitch has taken place, the contact Z" is first established, and thenthe contactjj as soon as the finger i enters the curve e", thiscorresponding to the entrance of the roller c into the concentricportion f of the lever f. At this moment the controlling-current passesfrom the battery .9 through the relay J, the switch I 1, the wire 2*,the contacts Z and F, f and f the rubbing con tact m, the contact 12,and the wire 1- the contact boxes or studs (Jr G, and returns by G tothe other pole. The controlling-circuit is thus completed and the relayJ is excited, breaking the contact J J and stopping the hell 25, but avery short time after the closing of the contact f the contact j closesalso, placing in short circuit the armature of the motor by way of thebrush Z2 to the spring j through j to the rubbing contact m, and by thecontact a" to the brush 7)". The brake is thus applied to the motor,which stops before the roller c arrives at the bottom of the slot f Assoon as the relay J is excited, as we have seen above, theelectromagnets D D are cut out of circuit and demagnetized. The bolt Cthen falls by reason of its weight until it is level with the table Aand no longer presents an obstacle to the passage of the detent B butwould present an obstacle to the lug B if it were desired to move backthe lever B. The lever B can therefore only be put over to the end ofits throw from the dotted position Fig. 8 to the position shown in Fig.9. Simultaneously with this final movement the switch I and thereversing-switch Gr Gr are moved. In fact, the first-named is moved bythe connecting-rod I from 1* onto 1 while the arm or plate G passes fromthe contact G: to the stud G and the arm or plate G passes from thecontact-stud G to the contact-stud G because the plate E is moved, byreason of the detent B striking against the tooth IF and carrying withit the connecting-rod G3 The switch 1" remains upon the contact 1 \Vewould remark that this final movement of the lever B to the positionFig. 9 can only be accomplished when all the contacts of thecontrolling-circuit have been closed in consequence of the completemovement and locking of the switch itself. The positions being as shownin Fig. 9that is to say, the switch set and locked for the branch orsiding track and the lever B in the corresponding position-thecontrolling-circuit is as follows: from the battery through the relay Jwhich is excited, by I I to the wire 2", to the contact I Z, thence toff to the rubbing contact m to the contact 117, and from here in twoportions, the one passing by the wire 1' to the contact G into Gr and by1' I to the other pole, the other portion passing from the contact 22through the bobbin u, the exciting-coil 1/ 1'1 the contact w the rubbingcontact 111 and the wire 1" to the other pole. Any rupture of one of thecontacts mentioned which may be caused by an external action acting todisplace the switch-rail will, as we have already explained withreference to the normal position, cause the ringing of the bell t andthe appearance of the indicator D Returning to Fig. 8, which shows theposition of parts when the motor is turning and moving the switch, wewill suppose that an obstacle placed between the point 0 and the rail 0"prevents the complete movement. Under these circmnstanccs the motorstops if it is not powerful enough to crush the said obstacle and thecontact Z Z is not made. The operator cannot therefore put the lever Bover to the full extent of its throw, and this tells him that the pointis not entirely set. He can then put back the switch to its initialposition by reversing the direction of the mo tor. This we haveindicated in Fig. 10, where there is shown the obstacle 0", whichprevents the closing of the switch. It is only necessary to put back thelever B as far as the top of the projection A that is to say, toward itsinitial position. In this movement the detent B comes against the end Hof the lever H H H and pushes same, this freeing the collar G10 from HThe spring Gr at once expands, pushing back this collar, which suddenlymoves the connecting-rod Gr and with it the reversing-switch G G. Thelever B is moreover arrested in the position shown, Fig. 10, by the boltG. which locks the detent B The connecting-rod G? has in its upwardmovement moved the plate E, and

the projection E of this plate has raised the detentB, while the detentBremains supported by the thrust of the lever H H H". The lever B is thenbent slightly back to the bottom of the projection A, and at thismovement the detent B is raised by the spring B. In these shortmovements the connecting-rod 1 does not move the switch I, this beingdue to the play which is provided at its joint at I by means of a slotgiving a suitable delay in the transmission at the moment when thischanges in direction. The arms or plates direction of the arrow 6 Gr Grof the reversing-switch upon coming onto the contacts G and Gr reversethe direction of the currentin the transmission-circuit. The distributer12 moves, and assuming the position shown, Fig. 10, modifies thecommunications in such manner that the current traverses theexciting-coil Z) in the reverse direction and the armature Z2 in thesame direction as previously; also, the motor begins to turn to theleft, driving the wheel 0 in the Further, the distributer insulates therubber 771* and puts the contact 91. in contact with the rubber mConsequently as soon as the switch-rail 0 is entirely applied againstthe rail 0 then, and only then, the contact Z Z is made, and then thecontact j 3, both in the controlling-circuit, and, finally, the contact3' which puts the armature in short circuit to brake and stop the motor.At this moment the controllingcircuit is complete, the current passesfrom the battery 8 through the relay J, which it excites, the switch II", the wire T the contacts Z Z and j the rubbing contact of, thecontact 72 the rubbing contact 172 the wire 1", and by G G to the otherpole. The relay J being excited, the electromagnet D D is no longerexcited and allows the bolt G to fall. This allows the lever B to bepushed to the end of its throw into its normal position behind theprojection A but not in the other direction, the lug B and the bolt Cpresenting an obstacle to this movement, all things being now as theywere described in referring to Fig. 7 In the movementthat is to say, inmoving the lever B from the position Fig. 10 to that of Fig. 7the detentB acts against the tooth E of the plate E to bring the reverser G G backupon the contacts G G by means of the connecting-rod G By the sameoperation the collar G is again brought into engagement under the end Hof the lever H H H Simultaneously the con necting-rod I moves the switchI and I to the end of their throw or travel.

In consequence of the symmetry of the different parts and sets ofcontacts the movement of the switch-rails from branch or siding track tothe main-line trackthat is to say, from the position Fig. 9 to theposition Fig. 7is effected in an entirely analogous manner to that whichwe have described for moving the switch-rails from the main-line trackto the branch or siding track.

We would remark that the controlling-circuit comprising the relay Jalways comprises a contact I I or I I, depending on the position of thetransmitting-lever, a corresponding line-wire r or 1 according to theposition, and in the switch apparatus a series of three contacts-viz., ZZ or Z Z governed by the position of the switch; j or 7' governed by thepresence of the roller e in the concentric locking-curve f or f m m or mn governed by the distributer. Consequently the operation of thecontrolling-circuit is governed by the fact of the position of theoperating-handle agreeing or being in harmony with the position of theswitch-rails and its being locked in this position and also with theposition or adjustment of the distributer, all being conditions whichtend to insure safety.

Having now described our invention, what we claim as new, and desire tosecure by Letters Patent, is-
